Is 8oz of water a day enough to surive on?

No, 8 ounces of water a day is generally not enough for survival. The average adult typically requires about 2 to 3 liters (approximately 68 to 101 ounces) of water daily to maintain proper hydration, depending on factors such as climate, activity level, and individual health. Consuming only 8 ounces can lead to dehydration and associated health issues over time. It's important to drink adequate fluids to support bodily functions and overall health.
